Measuring viscosity wirelessly
If precise mixing is a crucial process variable, viscosity measurement may be the most accurate way to ensure optimum performance. But rotating mixers can lead to very tangled wiring, so here Mark Ingham of Sensor Technology Ltd looks at wireless options.
HV coils - what are the key ingredients for lasting performance?
Industries that employ high-voltage (HV) rotating machines, either as generators or motors, are usually involved in sectors where loss of production can cost enormous sums of money. It is therefore essential that the original equipment and any repaired equipment be fitted with the best quality coils, and that any maintenance is carried out with precision and speed. Richard Emery, Head of Technical Services at the Sulzer Birmingham Service Centre, looks at the various aspects of the coil manufacturing process in order to provide a better understanding to those operating and maintaining these key pieces of equipment.
Servo technology is moving to a new paradigm
A long-standing engineers’ dream is to be able to assemble sophisticated, high-function, multi-axis servo systems from a kit of parts with no more difficulty than clicking Lego bricks together. Gerard Bush of Inmoco in Daventry says reality hasn’t quite caught up with fantasy, but it is moving in the right direction.
Conformance testing ensures clear open communications
Open control and automation networks, upon which devices from many vendors can be used, are increasingly preferred throughout most industrial sectors. John Browett, General Manager of the CLPA Europe explains the role and importance of conformance testing.
Optimised seals for wind turbine rotor, blade and tower bearings
Wind turbines must operate reliably in a diverse range of environmental conditions, both onshore and offshore. By optimising the bearing design, lubrication and sealing for wind turbine rotors, blades and tower, reliability and operating life are maximised, says Dr Steve Lacey, Engineering Manager at Schaeffler UK.
Specialised coatings improve enclosure performance
Specifying an enclosure for your application requires an understanding of the hazards that are likely to be encountered once installed, as well as the performance requirements that will be expected. Considerations such as tensile strength, security and ingress protection are relatively straightforward, and most well-manufactured enclosures should provide the necessary performance. But, how can an enclosure offer protection from extreme temperatures, electrical interference or any one of the thousands of other complications which can arise in industrial applications? Chris Lloyd, Spelsberg UK Managing Director, explains how specialised after-market coatings can enhance an enclosure’s performance in unexpected ways.
New opportunities and engineering services for machine builders
Jon Severn, editor of MachineBuilding.net, recently met John Renard, President of Cyient for the EMEA region, to find out what his company can offer UK machine builders.
Oil contamination is a major cause of machinery failure
Between 70 and 80 per cent of all hydraulic failures, which can lead to machinery failure, can be traced back to contaminated oil, according Bosch Rexroth
